Detection Systems for Neutron Radiography

Image detection methods for neutron radiography are described and capabilities of the methods in terms of exposure requirements, spatial resolution, and contrast are given. Neutron energy ranges cold, thermal, epithermal, and fast are included, but emphasis is on detectors for thermal neutron images. Image methods include photographic film, real-time, track-etch, gas-cell, and thermoluminescent; major emphasis is on film techniques, both direct exposure and transfer.
